Some new bits of paper to add to my Automotive Machining qualification. I fully recommend HP Academy for learning about EFI. Personally for me these courses are very basic but solidify my knowledge and refresh my understanding of tuning electronic fuel injected engines. Most of the fundamentals I have already learnt during my machining qualifications but not being able to turn the theory into practice is where these courses come to life. Andre Simon currently holds a NZ Drag Racing record which is recognised around the world. So if you want to learn from the best of the best I fully suggest paying for one of these courses.
